U.2 (SFF-8639) Single Port Interposers for PCI Express® 3.0 202 mm Key Features 7.95” 138 mm . Quick and simple set-up 5.4” . Allows capturing and decoding of all PCI Express traffic between 69 mm host and device 2.7” 105 mm . Decodes PCIe host interfaces 4.1” such as NVM Express (NVMe), SCSI Express (SOP/PQI), SATA Express (AHCI/PCIe) in addition to native PCI Express protocols 100 mm . Can be used with both 2.5” and 3” 3.9” drives . Supports data rates of 2.5 GT/s (Gen1), 5 GT/s (Gen2) and 8 GT/s (Gen3) Teledyne LeCroy’s U.2 (previously known as SFF-8639) single-port . Supports x2 SATA Express, x4 interposer cards provide quick and simple means for protocol analysis of NVM Express and x4 SCSI Solid State Drives (SSDs) based on PCI Express (PCIe®) protocols. The U.2 Express Interposer cards, used with a Summit Protocol Analyzer, enable PCIe bus traffic between a host backplane and SSD device to be monitored, captured, . Supports SRIS clocking and recorded for protocol analysis. The U.2 single port interposer supports . Supports CLKREQ# for testing PCIe host interfaces such as NVM Express (NVMe), SCSI Express low power L1 substates (SOP/PQI), SATA Express (AHCI/PCIe) and native PCI Express protocols at data rates from 2.5 GT/s up to 8 GT/s. Now it is possible to monitor and . Dimensions: analyze multiple PCIe storage host interfaces with a single set of tools. - 340 x 141 mm (13.4” x 5.6”) The U.2 interposers provide connectivity and monitoring capability for the recently announced U.2 connector targeted at enterprise storage devices. This U.2 connector provides flexible drive connectivity for NVM Express, SCSI Express, SATA Express, SAS, SATA, and native PCIe 3.0 host interface devices in a serviceable and hot-pluggable drive bay sometimes referred to as “Express Bay”. The U.2 single port interposers can be used with 2-1/2” or 3” sized drives. To use these interposers, the drive is inserted into a drive tray on the interposer that supports a mechanical and electrical connection to a U.2 connector. The interposer taps all PCIe protocol traffic between the host and the storage device and records it on the PCIe protocol analyzer, where protocol issues and performance metrics can be further analyzed and debugged. Teledyne LeCroy was the first company to introduce a PCI Express protocol analyzer with NVM Express decoding functionality. Since that time Teledyne LeCroy has added decoding for SCSI Express (SOP/PQI) and SATA Express (AHCI/PCIe). Integrating all three PCIe SSD technologies into a single protocol analyzer gives developers versatile tools that can show essential details regarding proper data transmission and bus performance. These tools have been at the center of much of the PCIe SSD interoperability testing that has occurred over the last few years. U.2 Interposer Interconnection Overview Analyzer connection for NVMe & SCSI Express Summit T34 Compatible with Analyzer connection Analyzer 2.5” and 3” drives for SATA Express only Straight iPass Cable (PE013UCA-X) For T28, T3-8 and T3-16, use iPass Y-Cable (PE010UCA-X) Device Under Test (DUT) U.2 Host Slot 12V DC from adapter supplied EXT Clock Input (optional) USB (Factory use only) Connecting the U.2 Interposers SW1: Clock Select 1. Set the DIP switches to the desired clock selection. Analyzer 12 Clock Note: “REF_CLK_A” should be the default setting unless you are using an external clock reference source. REF_CLK_A ON ON 2. Install the U.2 device under test (DUT) into the connector on the interposer EXT CLOCK OFF ON as shown (will fit 2.5” or 3” drives). 3. Connect the Summit T34 Analyzer (or other compatible Teledyne LeCroy Note: The SATA Express analyzer port is analyzer) to the interposer using the system iPass cable. labeled for 2.5 GT/s and 5 GT/s but also Note: On the Interposer side the iPass cable should be connected to the supports 8 GT/s. “x2 2.5GT/s / 5.0GT/s” port for SATA Express only. For all other applications, connect to the “x4 2.5GT/s / 5.0GT/s / 8.0GT/s” port (as shown in the diagram above). 4. Connect the analyzer to a host machine using the USB port on the front panel of the Summit analyzer. 5. If not already done, install the PCIe Protocol Suite software on the host machine. 6. Connect 12V DC using the AC adapter supplied with the interposer. (Make System Compatibility sure that the AC adapter is powered on). Summit T3-16 7. Power on the analyzer. Summit T3-8 8.
